  • Low CTE/CME boron/carbon fiber laminates and method of making them
    Patent number: 5593752
    Abstract: A boron/carbon fiber laminate comprising a boron fiber layer and a carbon fiber layer having a balanced pair of carbon fiber plies embedded in a plastic resin matrix has a Coefficient of Thermal Expansion between .+-.0.54 .mu.m/m/.degree.C., a Coefficient of Moisture Expansion between .+-.20.0 .mu.m/m/%.DELTA.M, and a specific modulus greater than 1.64.times.10.sup.6 meter. The laminate is useful for optical mounting structures.
    Type: Grant
    Filed: November 28, 1995
    Date of Patent: January 14, 1997
    Assignee: Eastman Kodak Company

  • Low CTE boron/carbon fiber laminate
    Patent number: 5554430
    Abstract: A boron/carbon fiber 1D laminate comprising a boron fiber layer and a carbon fiber layer having a balanced pair of carbon fiber plies embedded in a plastic resin matrix has a coefficient of thermal expansion between .+-.0.54 .mu.m/m/.degree.C. and a specific modulus greater than 8.9.times.10.sup.6 meter. A 2D boron/carbon fiber quasi-isotropic laminate having two sets of quasi-isotropic boron fiber plies, two sets of quasi-isotropic carbon fiber plies, the laminate has a Coefficient of Thermal Expansion between .+-.0.54 .mu.m/m/.degree.C. in two orthogonal directions, a specific modulus greater than 5.2.times.10.sup.6 meter in two orthogonal directions. The laminates are useful for optical mounting structures.
